Starting from rest, a 64.0 kg woman jumps down to the floor from a height of 0.610 m, and immediately jumps back up into the air. While she is in contact with the ground during the time interval  0 < t < 0.800 s,  the force she exerts on the floor can be modeled using the function F = 9,200t − 11,500t2 where F is in newtons and t is in seconds.   c) With what speed (in m/s) did she leave it? (Round your answer to at least three significant figures.) d) To what height (in m) did she jump upon leaving the floor?
